Almost 1,300 commercial vehicles were placed out of service for brake-related problems, during a one-day enforcement effort about two months ago.

The Commercial Vehicle Safety Alliance said law enforcement agents in 46 jurisdictions in the U.S. and Canada inspected 9,132 commercial motor vehicles on April 27. Of that number, 1,290 vehicles -- or 14.1% -- were placed out of service because of brake-related critical vehicle inspection item violations. Of that number, 1,228 were found in the U.S.

On April 27, 46 jurisdictions in Canada and the U.S. removed 1,290 commercial motor vehicles with brake-related critical vehicle inspection item violations from Canadian and American roadways. That’s 14.1% of the 9,132 commercial motor vehicles inspected during the unannounced one-day inspection initiative.

In addition, inspectors compiled and reported brake hose/tubing violation statistics, which was the focus area for this year’s Brake Safety Day. There were 1,534 brake hose/tubing violations. CVSA asked inspectors to submit data on four categories of brake hose/tubing chafing violations:

  • A category 1 violation is when the wear extends into the outer protective material. Thirty-two percent of brake hose/tubing chafing violations were identified in this category. A category 1 violation is not an out-of-service condition.
  • Category 2 is when wear extends through the outer protective material into the outer rubber cover. This is not an out-of-service violation. The largest category, 37% of brake hose/tubing chafing violations were category 2.
  • In category 3, wear has made the reinforcement ply visible, but the ply remains intact. Thirteen percent of brake hose/tubing chafing violations were identified as category 3, which is not an out-of-service violation.
  • In category 4, chafing has caused any part of the fabric/steel brain reinforcement ply to be frayed, severed or cut through. This is an out-service-condition. Eighteen percent of brake hose/tubing chafing violations were category 4.

On April 1, CVSA updated the North American Standard Out-of-Service Criteria to amend category 4 to make any tubing/hose damage resulting in the fabric/steel braid reinforcement ply being frayed, damaged or cut an out-of-service violation.

Compared to last year, the new category 4 brake hose/tubing chafing violations, as a portion of total brake hose/tubing chafing violations, increased modestly from 17% to 18%, even when accounting for what amounts to combining of categories 4 and 5 from 2021.

In addition, CVSA member jurisdictions equipped with performance-based brake testers (PBBTs) participated in Brake Safety Day activities, conducting 92 inspections with PBBTs, resulting in six, or 6.5%, commercial motor vehicles being placed out of service for insufficient overall vehicle braking efficiency.

CVSA conducts two major brake-safety inspection and enforcement initiatives each year. Brake Safety Week, is publicly announced well in advance and lasts for a week. This year’s Brake Safety Week is scheduled for Aug. 21-27.
